Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate global climate and energy problems. A research team has now introduced a novel and inexpensive material for electrodes that may provide for highly efficient, energy-saving hydrogen production: porous, phosphorized CoNi2S4 yolk-shell nanospheres.

Tropical rain forests are becoming fragmented at a higher rate than expected. By analyzing high-resolution satellite data, researchers were able to measure even the smallest piece of tropical forest and study the changes in tropical fragmentation. In a new paper, they discuss how this previously unnoticed and underestimated increase in fragmentation to almost one third of the forest area has consequences for the global carbon cycle.
